LamaPLC: TOFnnnC STMicroelectronics Time-of-Flight (ToF) sensors with I²C communication
The TOF050C, TOF200C, and TOF400C are a series of laser ranging sensor modules that use Time-of-Flight (ToF) technology to measure distances. They are designed for easy integration with microcontrollers such as Arduino and STM32 via the I²C interface.
These modules are based on different underlying STMicroelectronics chips, which determine their maximum measuring distances. They are commonly used in applications such as robot obstacle avoidance, altitude measurement for drones, and gesture recognition.
| Model | Ranging Chip | Max. Measuring Distance | Field of View (FoV) | Infrared Wavelength |

Pinout
| Pin Name | Type | Description |
|---|---|---|
| VIN | Power | Power supply input, typically 3.0V to 5.0V |
| GND | Power | Ground connection |
| SCL | I²C | Serial Clock line for I²C communication |
| SDA | I²C | Serial Data line for I²C communication |
| INT | Output | Interrupt output; can signal the MCU when data is ready (often labeled GPIO1 on the chip) |
| SHUT | Input | Shutdown control (Active Low); pull low to enter standby, high to enable (often labeled XSHUT) |
